Specification of Letters Patent.

Patented Apr. 22, 1919.

Application filed November 20, 1918. Serial No. 263,248.

To all whom it may concern:

Be it known that I, CARL SCHULTZ, a subject of the Emperor of Germany, residing at Richmond, county of Henrico, and State of Virginia, have invented certain new and useful Improvements in Washing-Machines, of which the following is a specification.

This invention. relates to improvements in ,washing machines and particularly to those adapted for domestic use.

The principal object of the invention is to provide an easily operated device in which the articles to be cleansed are given a churning motion upon a perforate plate in such a manner as to cause the water to thoroughly circulate therethrough.

A further object is to provide means which press upon the clothing in the manner 1 of an ordinary hand operated rub board so as to remove any accumulations upon the articles in a manner simulating hand action, and a i 7 Finally to provide a machine of the class mentioned which is easy to operate and requires but a minimum 'of physical energy.

These and other like objects are attained by the novel construction and combination of parts hereinafter described and shown in the acompanyingdrawings, forming a material part of this disclosure, and in which-- Figure 1 is a perspective view show ng a washing machine made in accordance w1th the invention.

- Fig. 2 is an enlarged vertical sectlonal view taken on line 22 of Fig. 1.

Fig. 3 is a transverse sectional view taken on line 33 of Fig. 2; and

Fig. 4 is a horizontal sectional view taken on line 44 of Fig. 2.

Referring to the drawings, the tank or container forming the body of the structure is comprised of side walls 10 and 11, seamed with the ends 12, which are formed integrally with the bottom plate 14 the lower corners 15 being curved as lndicated for purposes which will be hereafter apparent.

' A flanged marginal cover 16, extends unlformly inward and has secured at one end, by the hinges 18, a'hollow frame element 20, and engaged upon one of the longer sides of the frame 20, by hinges 21, is a door or cover plate 22, the same being provided with a loop handle 23 by which it may be conveniently raised, a similar handle 24 belng secured upon the frame 20, opposite the hinges 18-, so that this element may be raised when desired, while other handles 25 are fixed on the ends 12 of the outer tank so that the same may be readily moved from place to place when required.

Fixed upon the lower surface of the cover plate 22, are a pair of opposed brackets 27 .in which is rotatably mounted a horizontal shaft 28, the same being held against longitudinal movement by fixed collars 29, arranged interiorly of the brackets. Engage able with the squared end 30 of the shaft 28 is the enlarged end 31 of a sectional shaft 32 rotatably mounted in a sleeve 33 secured centrally of the side plate 10, the outer portion of the shaft 32 having fixed upon it the hub of an operating lever 35 which is operatively engaged therewith by the wing nut 36, threaded upon the extending end of the shaft, the arrangement being such that upon oscillating thelever 35, reciprocating rotary motion is conveyed to the'shaft 28 by the stub shaft'32 which may be withdrawn so as to permit the shaft 28 to be moved upward through the opening in the frame 20.

Loosely carried on the ends of the shaft 28, are hubs 38, formed centrally of a pair of longitudinally extending rails 39, the ends of which extend nearly to the inner surface of the end plates 12, so that the rails may oscillate freely therewithin.

Secured upon the shaft 28 are a pair of pulleys 40, the same being grooved so as to convey motion frictionally to cords 41, the ends of which are attached to vertical tubular elements 42, carrying rails 39.

These tubular rods 42 are rigidly secured together by a cross bar 44, and engaged in the lower ends of the elements 42, are rods 45, adapted to act telescopingly within the tubular elements 42. The lower ends of the rods 45 are rigidly engaged upon the outer side of, and centrally in the length of flat bars 46, having enlarged outer ends in which are journaled spindles 47 carrying rollers 48 arranged in pairs and having corrugated exteriors consisting of a plurality of longitudinal undulations, something in the manner of an ordinary hand wash rub-board in which laundry work is rubbed in the process of cleansin The peripherles of rollers 48 are adapted to rest upon a perforate plate 50 containing a plurality of openings 51, and journaled at its center upon extending spindles 52, the same being mounted in brackets 53, attached to the bottom 14 centrally of the casing,

while the ends 54: of the perforate plate 50 are curved upwardly in such manner asto prevent the articles being washed from passing 05 the ends of the plate. r

The operation of this apparatus is. as follows The cover 22 being raised, together with the rollers 48, which are relatively heavy,

the articles to be washed are disposed upon the perforate plate 50- ina relatively uniform manner, whereupon the Weighted rollers are lowered into position on top of the clothing and the mechanism assembled thereabove as indicated best in Fig. 2.

VThe operation consists in actuating the handle lever 35, giving it an oscillatory movement, thereby turning the grooved pulleys -10, causing the cords 4;l to move thereover and dueto their connection, forcing the rollers 48 to travel from end to end of the plate 50, causing it to oscillate by reason of the Weight of the rollers, while the Wheels 43, moving on the rails e9 oscillate them similarly and substantially parallel to the plate 50 the rails acting as guides only.

From-the foregoing it will be seen that articles to be laundried are alternately raised and lowered in the tank, which is filled partially with soapy water or other cleansing solution as preferred, and subjected to the action of therollers is, thereby effecting the task of laundrying SQiledclothing in an effective manner and at the expenditure of a minimum of physical energy. 35

Itis to be noted that no abrading or tearing of the articlesislikely to be encountered, while the water is caused to circulate through thesame, the operationbeing continued until desired results, have been attained.

,Having thus described my inventionwhat Copiea'of this patent maybe obtained for I claim as new and desire to secure by Letters Patent, is?

1. In a washing machine, the combination with an imperforate substantially rectangular tank and a cover hingedly engaged there with, of a perforate plate pivotally mounted in said tank adjacent to the bottom thereof, corrugated rollers arranged in pairs adapted to roll longitudinally of said perforate plate,

a rame onnecting a d crsya P ir of said plate extending substantiallyfrom end to end therewithin, pairs of weighted corrugated rollers m-orrable over the surface. of said perforate plate, a frame to vwhich said rollers areattached, means for guiding said frame, ,a shaft mounted below said cover, a stub shaft slidably and rotatably mounted within the walls of said tank, meansfor operating S i stub shaft, operative connections between said stub shaft and the first pulleys fixed upon named shaft, grooved said shaft and cords wound about said grooved pulleysand attached at their ends to said frame, whereby said rollers and frameare caused to operate, l
